No, no, no! Don't you read the responses?
One...more...time...

Dark matter move in curved (conic section) orbits in response to gravity, just like every other mass in the universe.

the DM that is around each galaxy is gravitationally bound to that galaxy
Again, the DM was there first and is more massive than the baryonic matter. So, technically, the galaxy is gravitationally bound to the DM, not the other way around.
As StupendousMan suggested, "Why don't you spend a few days reading some recent papers describing the formation of structure on galactic scales?"

Or a recent textbook on the subject.

Or even some recent articles on the subject in periodicals such as Scientific American and Sky & Telescope.
